Qualcomm ha annunciato una novità per quel che riguarda la ricarica senza fili, che permette ora di ricaricare dispositivi dotati di case metallici; il sistema si basa sulla nuova tecnologia sviluppata dall’azienda e denominata Qualcomm WiPower, conferme allo standard Rezence, ed è il primo in assoluto a poter garantire tale risultato.

Steve Pazol, General Manager of Wireless Charging in Quacomm Incorporated, ha affermato come tale tecnologia rappresenti un notevole progresso per l’intero sensore, dato il sempre maggior utilizzo di leghe metalliche per la realizzazione dei dispositivi, alla continua rincorsa di prodotti sempre più “premium”.

L’uso di leghe metalliche fornisce ai dispositivi maggior resistenza strutturale, oltre ovviamente ad un maggior pregio nel design e nell’estetica, ma crea problematiche nel caso dell’induzione magnetica sfruttata nella ricarica wireless. Qualcomm è riuscita a superare questi ostacoli, aprendo la strada all’uso di queste leghe senza dover limitare il supporto a tali modalità di ricarica.

WiPower lavora infatti ad una frequenza specifica in grado di essere più “tollerante” nei confronti degli oggetti metallici; i risultati hanno dimostrato la possibilità di ricaricare device che richiedano fino a 22W, oltre a garantire velocità di ricarica comparabili con quelle delle odierne tecnologie di ricarica rapida.

[spoiler title=”Comunicato stampa”] SAN DIEGO, Ca. – July 28, 2015 — Qualcomm Technologies, Inc., a wholly owned subsidiary

of Qualcomm Incorporated (NASDAQ: QCOM), today announced it has engineered a solution

to allow wireless charging for devices with metal exteriors. The solution, which uses

Qualcomm® WiPower™ technology, is designed to be compliant with the Rezence™ standard and

becomes the first announced solution to support wireless charging for metal devices, serving as

another proof point of Qualcomm Technologies’ commitment to innovation in wireless power.

The techniques for designing a device to charge through a metal back cover, as well as the full

suite of WiPower reference designs, are available today to WiPower licensees.

The ability to charge smartphones and other devices without wires offers unmatched

convenience to consumers, and until now, charging a device with a metal exterior has been

incompatible with wireless charging technologies.

“Building a wireless charging solution into devices with metal exteriors is a significant step for

moving the entire industry forward,” said Steve Pazol, General Manager of Wireless Charging,

Qualcomm Incorporated. “Today, more device manufacturers are choosing to utilize metal alloys

in their product designs to provide greater structural support and, of course, aesthetics. QTIs

engineering advancement eliminates a major obstacle facing wireless power and opens up the

continued adoption of this desirable feature to a much wider range of consumer electronics and

use cases.”

WiPower, as well as other technologies that meet the Rezence standard, operate at a frequency

that is more tolerant of metal objects that come within the charge field. Up to now, this meant

one could typically have objects such as keys and coins in the charge field and not affect the

charging process. Today, WiPower has added the ability to have the device itself made of metal.

This advancement maintains WiPower’s existing ability to charge devices requiring up to 22

watts today, at speeds equal to or faster when compared to other wireless charging technologies.

Based on Near Field Magnetic Resonance technology, WiPower enables greater flexibility and

convenience in wireless charging, allowing a wide range of compatible consumer-electronic and

handset devices to charge without the need for precise alignment or direct physical contact.

Additionally, the technology enables simultaneous charging of multiple devices with different

power requirements while using Bluetooth Smart to minimize hardware requirements.

As a founding member of the Alliance for Wireless Power (A4WP), Qualcomm is actively

engaged in the advancement of wireless charging, becoming one of the first member companies

to receive Rezence certification on multiple receiver and transmitter designs.
